Anal sex is totally prohibited and is considered a grave sin whose doer is cursed and incurs the wrath of Allah. The Prophet (peace and blessings be upon him) is reported to have said: “cursed is he who has had sex with a woman in her anus.”

As for oral sex, there is no proof for its prohibition and thus it is considered permissible between a husband and his wife. However, it is something that seems disgusting to a lot of people; in addition to the fact that these parts of the body usually attract more germs and microbes than other parts.
